Django Admin Integration

Seamlessly integrated into your Django admin interface. A new section for dj-redis-panel will appear in the same places where your models appear.

NOTE: This application does not actually introduce any model or migrations.

Instance Overview

Monitor your Redis instances with detailed metrics and database information.

Key Search - Page-based Pagination

Search for keys with traditional page-based navigation.

Key Search - Cursor-based Pagination

Efficient cursor-based pagination for large datasets.

Key Detail - String Values

View and edit string key values with TTL management.

Key Detail - Other data structures

Browse keys with more complex data structures such as hashes, lists, etc.

Installation

1. Install the Package

pip install dj-redis-panel

2. Add to Django Settings

Add dj_redis_panel to your INSTALLED_APPS:

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'dj_redis_panel',  # Add this line
    # ... your other apps
]

3. Configure Redis Instances

Add the Django Redis Panel configuration to your Django settings:

DJ_REDIS_PANEL_SETTINGS = {
    # Global feature flags (can be overridden per instance)
    "ALLOW_KEY_DELETE": False,
    "ALLOW_KEY_EDIT": True,
    "ALLOW_TTL_UPDATE": True,
    "CURSOR_PAGINATED_SCAN": False,
    
    "INSTANCES": {
        "default": {
            "description": "Default Redis Instance",
            "host": "127.0.0.1",
            "port": 6379,
            "db": 0,
            # Optional: override global settings for this instance
            "features": {
                "ALLOW_KEY_DELETE": True,
                "CURSOR_PAGINATED_SCAN": True,
            },
        },
        "other_instance": {
            "description": "Cache Redis Instance",
            "url": "rediss://127.0.0.1:6379",
        },
    }
}

4. Include URLs

Add the Redis Panel URLs to your main urls.py:

from django.contrib import admin
from django.urls import path, include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('admin/redis/', include('dj_redis_panel.urls')),  # Add this line
]

5. Run Migrations and Create Superuser

python manage.py migrate
python manage.py createsuperuser  # If you don't have an admin user

6. Access the Panel

1. Start your Django development server:

   python manage.py runserver
   

2. Navigate to the Django admin at http://127.0.0.1:8000/admin/

3. Look for the "DJ_REDIS_PANEL" section in the admin interface

4. Click "Manage Redis keys and values" to start browsing your Redis instances

Configuration Options

Global Settings

Setting	Default	Description
ALLOW_KEY_DELETE	False	Allow deletion of Redis keys
ALLOW_KEY_EDIT	True	Allow editing of key values
ALLOW_TTL_UPDATE	True	Allow updating key TTL (expiration)
CURSOR_PAGINATED_SCAN	False	Use cursor-based pagination instead of page-based

Instance Configuration

Each Redis instance can be configured with:

Connection via Host/Port:

"instance_name": {
    "description": "Human-readable description",
    "host": "127.0.0.1",
    "port": 6379,
    "db": 0,                    # Optional, default: 0
    "password": "password",     # Optional
    "features": {               # Optional: override global settings
        "ALLOW_KEY_DELETE": True,
    },
}

Connection via URL:

"instance_name": {
    "description": "Human-readable description", 
    "url": "redis://user:password@host:port/db",
    "features": {               # Optional: override global settings
        "CURSOR_PAGINATED_SCAN": True,
    },
}

Feature Flags

Feature flags can be set globally and overridden per instance:

• ALLOW_KEY_DELETE: Controls whether the delete button is enabled
• ALLOW_KEY_EDIT: Controls whether key values can be modified
• ALLOW_TTL_UPDATE: Controls whether key expiration can be updated

Development Setup

If you want to contribute to this project or set it up for local development:

Prerequisites

• Python 3.9 or higher
• Redis server running locally
• Git
• Autoconf

1. Clone the Repository

git clone https://github.com/yassi/dj-redis-panel.git
cd dj-redis-panel

2. Create Virtual Environment

python -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate

3. Install dj-redis-panel inside of your virtualenv

A make file is included in the repository root with multiple commands for building and maintaining this project. The best approach is to start by using one of the package installation commands found below:

# Build and install a wheel for this project
# Also install all dev dependencies such as pytest and other utilities
make install_dev

# Build and install a wheel for this project
make install

# build and install all dev dependencies and run all tests
make test

4. Set Up Example Project

The repository includes an example Django project for development and testing:

cd example_project
python manage.py migrate
python manage.py createsuperuser

5. Populate Test Data (Optional)

An optional CLI tool for populating redis keys automatically is included in the example django project in this code base.

python manage.py populate_redis

This command will populate your Redis instance with sample data for testing.

6. Run the Development Server

python manage.py runserver

Visit http://127.0.0.1:8000/admin/ to access the Django admin with Redis Panel.

7. Running Tests

The project includes a comprehensive test suite. You can run them by using make or by invoking pytest directly:

# run using make which will also install all dependencies (recommended)
make test

# run using pytest directly
pytest tests/

# Run with coverage
pytest tests/ --cov=dj_redis_panel

# Run specific test file
pytest tests/test_views.py

Note: Tests require a running Redis server on 127.0.0.1:6379. The tests use databases 13, 14, and 15 for isolation and automatically clean up after each test.

8. Dockerized Redis

Test for this project (as well as any active development) require an active redis installation. Although not required, a docker-compose file is included to allow for easy creation of local redis instances.

# Start Redis on localhost and the usual port 6379
docker-compose up redis -d
